Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

Question

Help with a iv, b and c

(a) X-rays scattered by the outer electrons in the atoms of a sample
of crystal are detected at an angle 0 = 152° . The detected x-
rays have a wavelength of 0.1865 nm. Assuming the electrons
can be considered to be 'stationary', i.e., at rest, before they
scatter the x-rays
i. Find the wavelength of the incident photons.
ii. Find the energy of the incident photons.
iii. Find the speed of the electrons after they scatter the pho-
tons.
iv. At what angle would the wavelength of the scattered x-rays
be a maximum? Determine the wavelength of the x-rays
scattered at this angle for the incident wavelength found in
(a).
(b) Suppose instead that the incident x-ray photons in part (a) are
scattered by neutrons or protons. Compared with the scattering
of x-rays by electrons that occurs in part (a), what differences
and similarities would you expect?
(c) Explain how x-rays in a suitable energy range can be used to
study the structure of crystals.
